Document Summary
Answer any 10 of the following 12 questions. Each is worth 7 marks: the change in temperature between the warmest and coolest parts of the day measures the sun"s thermal heating of the earth (called diurnal temperature variation). Temperature changes (in f) for ten days are recorded as follows: 16. 0 (a) determine the median, and also the rst and third quartiles. Page 2 of 5: (a) a hockey goalie has a 0. 89 chance per shot of preventing a goal. What is the probability that, out of ten shots taken, exactly one goal occurs. (b) for a recent period of 100 years, the average number per year of major earthquakes (at least 6. 0 on the richter scale) was 0. 93. Poisson distribution is a suitable model, nd the probability that no earthquakes occur in a year. (c) in an experiment for cross-breeding, there are eight tropical sh of which ve are female.
